Dissociative recombination ofHeH+at large center-of-mass energies

Abstract
Dissociative recombination of HeH+ has been studied for the HeH+ ion stored in a storage ring. A strong recombination resonance having a peak at around 20 eV center-of-mass energy has been found for the first time in addition to the known recombination at around 0 eV center-of-mass energy. The strength of the recombination rate changes depending on the storage time of HeH+ ions.
